Tweak fuel pressure, then monitor line pressure with ECS Tuning Adjustable Fuel Pressure Regulators and inline Fuel Pressure Gauge Kits.

Based on a Bosch regulator, our metal-bodied adjustable regulator is an exact-fit replacement for the stock unit. Its integral adjustment screw lets you change rail pressure, and its vacuum-sensing port automatically compensates for the pressure drop across the injectors at different engine loads.

Add our 0-100 psi pressure gauge, individually, or as part of a kit, and take the guesswork out of fuel pressure monitoring and adjustment.

Tweak and Test for Added Performance.

Fits:
Audi B5 A4 (1996-2001)

Audi MKI TT (1998-2007)
